' 4 Claims; (Cl. 33-197) The present invention relates to an improved which is primarily adapted to instrumentality I the same being susceptible be used by carpenters, of appropriate identification, purpose is to greatly assist a carpenter in laying out and thereafter completely chiseling'a mortise. v

Although mortises for butt hinges are produced in a number of differentIways with saws,

sive or widespread use, suggests that a preferred as'a templet whose type of universally 'useable templet has, presumably not yet been contrived and brought into common useage. It is thereforethe object of the instant endeavor to' structurally, functionally and otherwise improve upon known mortising templets and, in so doing, to provide one in which manufacturers, hardware sellers and carpenters willfind their respective requirements and needs satisfactorily met.

Another objective, generally'speaking, is to simplify and thus improve upon and reduce the number of parts entering into the combination, thereby not only increasing the efficiency of the structure as a whole, but rendering same less costly to manufacture and, in addition, to sim plify factors of assembling and sale.

More specifically, novelty is predicated on a marking templet to assist one in chiseling and a hinge butt seating mortise comprising a flat faced frame defining a chisel confining mortise outlining opening, and shoulder means integral with said frame, said meansbeing at right angles to an adjacent face of said frame.

More particularly, the invention appertains to the aforementioned frame wherein the latter is rectangular and. defines a rectangular chisel accommodating opening whose marginal edges serve to locate the chisel in properly delineating and partially cutting the mortise. In addition, there is a slot along one longitudinal edge portion of the frame and has associated therewith shoulder means and the slot and shoulder means serve to accommodate an insertable and removchisel, the same chisel which lays out the mortise, whereby to provide a satisfactory way of gauging the depth of the finished mortise.

. bar also has its opposite tion 28 projecting beyond the edge 20 of the Other objects, features and advantages will become more readily apparent from the follow ing description and the accompanying sheet of illustrative drawings. f

In the accompanying sheet of drawings, wherein like numerals are employed togdesignate like parts throughout the views:

Figure 1 is a face or side elevational view of a templet constructed in accordance with the prin-a ciples of the present invention; Z 1

Figure 2 is alike elevational tions broken away, observing the reverse sideof said templet;

Figure 3 is a section on'thehorizontall ine 1-4 of Figure 1 looking'in the direction of the arrows; v

Figure 4 is a view on'a'reducedscale showing one method of using the templet' and chisel on the marginal edge of a door or the like; my

Figure 5 is a similar view showing how the templet isattached and ,used on the'ja'mb" or frame as it is sometimes preferably called.

Referring now to the drawings with the aid of reference numerals and accompanying lead lines the templet is characterized primarily by a substantially rectangular flat face plate; The plate has opening means'of rectangular form cut therein and the opening means is denoted at 6 and the plate which now becomes a rec tangular frame is denoted bythe numeral 1. The opening means provides marginal edge's 8 and I0 and Hto assist in placing the chisel blade when outlining or marking off the size and shape of the desired mortise. ,There'is a lug or ear I; also provided and thisflis integral with the frame and it projects into the opening means where it is provided with a hole l4 to'accommodate a headed fastenersuch as a screw or the like (not shown) The plate or frame is provided along the marginal edge [6 with additional'holes I8 to accommodate suitable fastenings (shown onlyinFigure 5).

Along the marginal edge 2 0'the frame is provided with cooperating slot and shoulder means. More specifically this means comprises a flat metal strip or barmember 22 which is opposed to the left hand side of the template in the drawings and has its end portions joined there; to by spacers 24 asperhaps best shown inFigure 3. One. longitudinal edge of member, 22 is ltaerally deflected and forms a flange 26 and this registers with the edge or margin 8 of the open-- ing means 6 and it functions as a placement shoulder as evident from Figures 4 and 5., The

longitudinal edge porprojecting edge portion 28 frame in defining a pilot main frame and this cooperates with the for the blade 30 of the chisel 32. This pilot assists in guiding and delivering the chisel blade into the depth regulating slot means 34.

which can be manufactured in different dimen slons.

When the device is to be used onthe con-fronting edge 36 of the door 38 it is applied and fastened as shown in Figure 4. Here the frame is placed firmly and properly against .the surface 36 with the lug or car l2 superimposed on said surface and temporarily secured thereto' by a screw or other equivalent fastening 40 passing through the hole M. In some doors the thickness may be such that it is also possible to use the holes. I8-I8 for additional fasteners. In any event the outstanding flange or shoulder 26 bears against the surface 42 of the doorv and this disposes the slot means in a position at right angle to and beyondsaid surface 42. The chisel is first operated in an obvious manner within the marginal limitsof the opening means 6. The blade of the chisel may be placed against the respective edges 8, 9, H) and II and in this way the mortise is partly cut out but is primarily delineated instead of marking it with a pencil such as is. sometimesdone. In other words, here we have the step of marking the mortise and also partly cutting out the mortise. The next stepconsists in. placing theblade 30 of the chisel 32 into the slot means 34 at which time the partly severed piece of wood or a plug isfineiy and nicely gouged out, this also in an obvious manner. After the principal plug is removed the smaller plug which is defined by the ear I 2 may be chiseled out. As is the situation with other tools and instrumentalities the device herein becomes an easy thing to set in position, fasten and serve its immediate purposes. This depends largely on the experience of the carpenter who, once he becomes familiar with the use of the instrumentality, will unquestionably resort to it when cutting any and all mortises for butt hinge mounting purposes.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. .Therefore, a more lengthy description is. regarded as unnecessary.

. Minor changes in th shape, size and arrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.

Having described the claimed as new is:

1. A marking templet to assist one in chiseling 'and gouging out a hinge butt seating mortise comprising a frame defining a chisel confining mortise outlining opening, said frame being rectangular and fiat throughout its area and said opening being essentially rectangular, said frame having marginally arranged holes to accommodatev frame anchoring fasteners and also having an integral apertured attaching ear coplanar invention, what is 4 with the frame and projecting into said outlining opening, and shoulder means integral with said frame, said means being at right angles to an adjacent face of said frame and being flush with one cooperating longitudinal edge of said outlining opening.

2. The structure defined in claim 1, wherein said shoulder means also embodies slot means into which a chisel is fitted and used to gouge out the portion of the wood which defines said mortise.

3. A marking templet to assist one in chiseling and gouging out a hinge butt accommodating and seating mortise comprising a wholly fiat sub- "stantiallyrectangular frame having marginally arranged holes to accommodate frame anchoring fasteners and defining a centered chisel confining and accommodating opening, one frame member being provided with a coplanar ear and said ear projecting into said opening and having a hole therein to accommodate a fastener, a flat face bar member paralleling one longitudinal edge portion of and spaced from said frame and having one longitudinal edge projecting beyond the adjacent edge .of the frame and having the opposite longitudinal edge portion formed with a stop flange, said bar cooperating with said frame in'defining a chisel accommodating slot.

4. A mortise scribing and chiseling template comprising a perfectly and wholly fiat rectangular frame defining an essentially rectangular opening, the outer marginal edge of one longitudinal frame member having holes to accommodate headed fasteners, the inner marginal edge of said one frame member having an integral coplanar attaching ear, the latter having a fastener hole therein and projecting into said rectangular opening, a fiat rectangular bar member of a length commensurate with the length of said frame and opposed in spaced parallelism to one surface of the other longitudinal frame member, the opposite transverse ends of said bar member being integrated with corresponding ends of said last named longitudinal frame member by way of spacers, said latter frame member and bar member providing a chisel slot and said slot being of a length at least equal to the overall length of the aforesaid opening, the width of said bar member being greater than the width of said last named frame member and having its outwardly disposed longitudinal edge projecting beyond the corresponding edge of said frame member and providing a chisel piloting member registering with said slot, the inner longitudinal edge of said bar member having an integral flange projecting laterally in a direction away from the adjacent surface of said frame, one face of said flange providing a stop shoulder and the latter being coplanar and therefore flush with the inner longitudinal edge of said last named frame member.
